With more than 150,000 lots and one million specimens, the MZUSP Mollusc Collection is the largest in Latin America.
The representation of the collection is worldwide, but with greater emphasis on the Neotropical region and West Atlantic coast. It also has over 1,200 type specimens . Such representativeness continues to grow, with collections and research projects, as well as the purchase of collections and exchanges, which has made the Mollusc Collection increasingly important in the context of global Malacology. About 2/3 of the collection is kept in wet. The lots are packed in special flasks, in sliding compactor cabinets.
